Dude, tons of difference. Way more natural and organic, awesome colors, expression, etc. Maybe take a break from studies for a day or two and pump out some more fun stuff I feel you're the boldest with colors, composition, etc. when you're drawing stuff you're familiar with, explore that!

Aww, thanks dude! That's actually what I did today! I did this pic here, and then this: [link] I might do a bigger painting or play around with this stuff a bit more, but I must admit I have burnt myself out a bit on grinding so much...

I just want to improve as fast as possible, y'know? But I must admit I have started to dread grinding each day lol. Maybe I'll tone it down a bit, but I don't think I should completely stop with it, even if just for a few days.
